Vim li cas cov voltage nruab nrab ntawm nruab nrab hlau thiab cov nyob hlau 380v thaum ntsuas los ntawm tus malcimeter?
Qhov siab tshaj plaws uas muaj peev xwm ua tau rau cov kab hluav taws xob nruab nrab thiab cov khoom siv hluav taws xob nrog lub sijhawm 380V yog tias thaum lub sij hawm saib xyuas hluav taws xob ib puag ncig (txawm hais tias qhov xwm txheej no muaj tsawg kawg nkaus, Nws tsis tuaj yeem kav tau tias nws yuav tshwm sim).
Ib txhia thiaj li hu ua "cov kws tshaj lij" yam tsis muaj kev ntseeg ntawm kev ua piv txwv thiab teb cov xov xwm hluav taws xob muaj kev sib txuas ntawm 380v ntawm cov xaim hluav taws xob. Vim tias lub nruab nrab ntawm lub ntsej muag ntawm peb-theem thauj khoom tshwm sim los ntawm kev qhib ntawm txhua theem ntawm txhua theem rau tus neeg siv khoom, thiab tseem yog qhov xwm txheej ntawm txoj kab li ntawm txoj kab nruab nrab yog qhov chaw nruab nrab; Cov cuab yeej siv hluav taws xob muab rau los ntawm cov neeg siv sib txawv yuav muab cov khoom siv hluav taws xob sib txawv los ntawm cov khoom siv hluav taws xob sib txawv vim muaj cov khoom siv sib txawv tas li ntawm txhua theem.
uas yog; Yog tias lub nruab nrab ntawm lub peb-theem thauj khoom yog tshwm sim los ntawm cov khoom loj me me, suav nrog kev faib tawm ntau dua thaum lub sij hawm sib zog ua ke xws li siv sijhawm ntau zaus, thiab lwm yam.) (cov khoom siv hluav taws xob) nruab nrab ntawm peb-theem cov neeg siv tau qhib thiab hlawv tawm, yog tias tsis ua raws sijhawm; Thaum kawg, feem ntau ntawm cov khoom siv hluav taws xob (khoom siv hluav taws xob (khoom siv) nyob rau hauv tag nrho cov chaw xa tawm yuav hlawv tawm.
Kuv nyuam qhuav nkag tau nrog peb-theem AC fais fab, thiab cov xaim xaim thiab nruab nrab yog raws nraim 220v, uas tseem yog hom siv hauv tsev. Qhov muaj peev xwm sib txawv ntawm cov xov hlau theem yog qhov tseeb 380v. Hauv lwm lo lus, nws yog feem ntau yuav yog ib qho ntawm cov qib hauv theem hauv koj lub tsev tau txuas nrog lub xaim xaim nruab nrab, ua rau muaj peev xwm sib txawv ntawm 380V.
Yog tias qhov xwm txheej no tshwm sim hauv tsev, nws yog ib qho tsim nyog los txiav txim siab ntiav cov neeg ua haujlwm daws teeb meem, txwv tsis pub cov hluav taws xob siab tuaj yeem hlawv cov khoom siv hluav taws xob.
Seb qhov no yog qhov xwm txheej tuaj yeem raug txiav txim yooj yim tau yooj yim. Koj tuaj yeem nrhiav tus cwj mem hluav taws xob thiab ntxig rau hauv ob lub qhov (socket) ib qho los ntawm ib qho los saib yog tias txhua qhov chaw muaj hluav taws xob. Yog tias muaj hluav taws xob hauv txhua qhov xwm txheej uas kuv tau piav qhia, qhov chaw nruab nrab yog txuas nrog theem xaim xaim. Kuv pom tias cov neeg siv tseem ceeb ntsuas lub voltage nrog multimeter multimeter, qhia tias lawv muaj compimeter hauv tsev. Koj tuaj yeem ntxig qhov kev sojntsuam liab ntawm ntau ntau rau hauv lub qhov (socketately, tab sis tsis txhob ntxig qhov kev sojntsuam dub. Txawm li cas los xij, sim tsis txhob kov cov kev sojntsuam dub nrog koj txhais tes. Yog tias muaj cov hluav taws xob hauv ob qho tib si thom khwm, nws kuj tseem tuaj yeem xaus lus tias qhov xwm txheej no tau hais txog.
